When Does Memory Loss Warrant an Alzheimer’s Disease Evaluation? What a Neurologist Rules Out

The car keys were in the freezer. That part, honestly, everyone laughed about. What kept Marian’s daughter awake was the phone call two days later, when her mother described a neighbor’s funeral in detail and then, ten minutes on, asked whether anyone had heard how the neighbor was doing.

Moments like that send families to a search bar and eventually to a question that feels heavier than it should: is it time to see a neurologist for memory loss, or are we overreacting to ordinary aging? Both fears are legitimate. Nobody wants to medicalize a forgotten name; nobody wants to miss a treatable cause while the calendar quietly moves on.

The honest answer is that the evaluation is less about proving Alzheimer’s disease and more about methodically ruling out everything else. Once you understand how that process works, a dreaded appointment turns into something far more useful: information you can act on.

Is my forgetfulness normal aging or something more?

Everyone loses a word now and then. The trouble is that ordinary forgetting and worrying forgetting look alike from a distance, so it helps to know what separates them up close.

Age-related change tends to affect speed and retrieval. You know the actor’s name; it simply arrives three hours late. You walk into a room and need a beat to remember why. Harvard Health describes several of these patterns, including transience, absent-mindedness and blocking, as ordinary features of a healthy brain rather than early signs of disease. Crucially, a cue works: someone offers the first syllable and the whole name lands.

Forgetting that concerns a clinician has a different texture. The information was never stored, so a hint does not help. Yesterday’s conversation is not fuzzy; it is gone. Tasks that used to be automatic, such as balancing a checkbook, following a recipe or driving a familiar route, start to demand effort or go wrong. And the pattern of who worries is often reversed: the person with a benign lapse tends to be the one fretting about it, while in early dementia it is frequently a spouse or adult child who notices first.

Two more distinctions matter. Direction: isolated lapses stay flat across the years, while a disease process progresses, sometimes so slowly that families date it by holidays rather than months. And breadth: memory alone is one thing; memory plus trouble with words, judgment, spatial sense or mood is another.

None of this is a test you can pass or fail at home. It is vocabulary for describing what you have seen, which is exactly what a neurologist will ask for.

When should you see a neurologist for memory loss, and who is usually asked to wait?

A neurologist is a physician trained in disorders of the brain, spinal cord and nerves. Not every memory complaint needs one. Most guideline pathways, including the one the NHS describes, begin with a primary care clinician who can screen, order initial blood work and refer onward when the picture warrants it.

Referral to a neurologist or memory clinic is typically considered when the change is persistent rather than a bad week, when it is progressing, when someone else has noticed it, or when it has started to interfere with independent living: money, medications, appointments, driving, cooking safely. Referral is also considered when the pattern is unusual for age, meaning symptoms beginning before roughly 65, rapid decline over weeks or months, or memory trouble arriving alongside tremor, unsteady walking, hallucinations, personality change or new incontinence. Those combinations point toward conditions other than typical Alzheimer’s disease and benefit from a specialist’s eye early.

Who is usually asked to wait, or more accurately to be re-checked rather than referred immediately? Someone whose lapses are stable, who is worried but functioning fully, and whose primary care screen and blood tests come back unremarkable. Someone in the middle of an obvious stressor, whether bereavement, a new sedating medication, untreated sleep apnea or a recent hospitalization, where the sensible first move is to address that and reassess. Waiting in this sense is active: a follow-up date is set, and a changed picture reopens the door.

The decision belongs to the clinician who knows the history, but the threshold is lower than many people assume. Persistent concern from a family member is a legitimate reason for an evaluation on its own.

Which doctor is best for memory loss? Primary care, geriatrician or memory loss specialist

People type this question constantly, and the honest answer is that it depends on the stage of the question, not on prestige.

Primary care is the usual front door. A family physician or internist knows your baseline, can review every medication in the cabinet, order thyroid and vitamin B12 tests, screen for depression and administer a brief cognitive screen in a routine visit. For many people the story ends there, with a reversible cause found or reassurance given.

A geriatrician is a physician who specializes in the health of older adults. Geriatricians are especially valuable when memory trouble sits alongside several other conditions, such as heart failure, diabetes, falls or a long medication list, because they are trained to weigh how those interact with thinking.

A neurologist is what most people mean by a memory loss specialist, and for good reason. Distinguishing Alzheimer’s disease from vascular disease, Lewy body disease, frontotemporal degeneration, normal pressure hydrocephalus or a seizure disorder is squarely neurological work, and neurologists order and interpret the imaging and fluid tests involved. Some subspecialize in behavioral neurology or dementia.

A neuropsychologist is a psychologist with doctoral training who administers detailed, standardized cognitive tests over several hours and maps the pattern of strengths and weaknesses. They do not prescribe. They provide the fine-grained profile that helps a neurologist tell one condition from another and can say with some confidence whether scores fall outside what is expected for age and education.

Geriatric psychiatrists join when mood, anxiety or behavioral symptoms dominate. Many memory clinics deliberately gather several of these disciplines together, which is why asking about a memory or cognitive clinic referral is often the most efficient route.

What does a neurologist do for memory loss at the first visit?

The first appointment is mostly conversation, and the most valuable person in the room is often not the patient but the companion who has watched the change unfold. Come with both.

The neurologist will want a timeline: when anything first seemed off, what was noticed first, how it has changed since, whether onset was gradual or sudden. They will ask what the person can and cannot still do independently, the so-called instrumental activities of daily living such as finances, medications, shopping, cooking and transport, because function rather than a test score is what separates mild cognitive impairment from dementia. Expect questions about mood, sleep, snoring, alcohol, head injuries, hearing and vision, and a medication review that includes over-the-counter sleep aids and allergy pills, several of which carry anticholinergic effects that can cloud thinking in older adults.

Family history matters, particularly for early-onset patterns. So do education and occupation, because cognitive screens are interpreted against what someone’s brain could do before.

Then comes the examination. A neurological exam checks eye movements, facial symmetry, strength, reflexes, coordination, sensation and, especially, gait. How someone walks tells a neurologist a surprising amount. A shuffling, wide-based step raises the question of normal pressure hydrocephalus; slowness and stiffness with a tremor point toward parkinsonian conditions such as Lewy body disease; one-sided weakness hints at prior stroke.

Finally, a brief cognitive screen is administered in the room and initial tests are ordered. NIH’s National Institute on Aging notes that no single test confirms Alzheimer’s disease; the diagnosis is assembled from history, exam, cognitive testing, laboratory work and imaging read together. That is why a first visit rarely ends with a name. It ends with a plan.

What is the neurologist memory test, and what does the score actually mean?

People often arrive braced for a pass-or-fail exam. What actually happens is a short, structured screen, commonly the Montreal Cognitive Assessment (MoCA) or the Mini-Mental State Examination (MMSE), that samples several thinking skills in a handful of minutes. The names appear here because patients will see them on paperwork, not because one is superior.

The tasks feel simple: recall a short word list after a delay, draw a clock showing a specific time, copy a cube, name animals, repeat a sentence, subtract sevens, state the date. Each probes a different function, from memory to visuospatial skill, language, attention and orientation, and the pattern of misses can be as informative as the total. Someone who draws a distorted clock but recalls every word is telling a different story than someone who does the opposite.

A score is a signal, not a diagnosis. Screens are swayed by education, language fluency, hearing, anxiety, sleep and even the hour of the day. A person with a graduate degree may score in the normal range while genuinely declining from a very high baseline; someone with limited schooling may score low with no disease at all. Mayo Clinic describes these tools as a starting point that determines whether more detailed testing is warranted.

That detailed testing is neuropsychological evaluation: several hours, often split across sessions, of standardized tasks compared against norms for age and education. It can distinguish a retrieval problem typical of depression or vascular disease, where hints help, from a storage problem typical of Alzheimer’s disease, where they do not. Just as valuable, it establishes a baseline. Repeating the same battery a year later answers the question no single visit can: is this changing?

What a neurologist rules out first: reversible causes of memory loss

Here is where the appointment earns its keep. Before Alzheimer’s disease enters the conversation, a neurologist works through conditions that can mimic it and can be treated.

Delirium comes first because it is urgent. Delirium is an acute state of confusion that develops over hours to days, often with fluctuating alertness, triggered by infection, dehydration, medication changes, surgery or pain. MedlinePlus lists it among causes of memory loss needing prompt attention. It is not dementia, though it strikes people with dementia more readily.

Depression can blunt concentration and retrieval so thoroughly that it was once called pseudodementia. Mayo Clinic notes that depression and Alzheimer’s disease can also coexist, so treating mood is both a diagnostic step and a therapeutic one.

Medications are a frequent, overlooked culprit: sedatives, older antihistamines, bladder antispasmodics, some pain relievers and sleep aids. The fix may be a conversation with the prescriber, never a change made at home.

Blood tests screen for underactive thyroid, vitamin B12 deficiency, kidney and liver dysfunction, abnormal sodium or calcium and, where history suggests, infections.

Sleep matters more than most people expect. Obstructive sleep apnea, repeated pauses in breathing during sleep, fragments rest and starves attention. Heavy alcohol use, uncorrected hearing loss and untreated vision problems all degrade the raw material the brain has to work with.

Two structural causes are checked on imaging. Normal pressure hydrocephalus is an accumulation of fluid in the brain’s cavities that produces gait difficulty, urinary urgency and cognitive slowing. A chronic subdural hematoma is a slow bleed under the skull after even a minor fall. Both may be treatable with surgery, and both can be missed without a scan. Ruling them out is not a formality; it is the point.

Blood tests, brain scans and spinal fluid: what each can and can't show

Testing moves from broad to specific, and it helps to know what each layer is for.

Routine blood work, described above, looks for treatable contributors. It cannot show Alzheimer’s disease. Blood-based biomarker tests that measure amyloid or tau, the two proteins that accumulate abnormally in Alzheimer’s, are entering specialist practice, but NIH’s National Institute on Aging describes them as still being validated for routine clinical use. Ask your neurologist whether such a test would change decisions in your case.

Structural imaging, meaning an MRI or a CT scan if MRI is not possible, shows the shape of the brain. It can reveal strokes, tumors, bleeds, hydrocephalus and patterns of shrinkage. In Alzheimer’s disease the hippocampus, a seahorse-shaped memory structure deep in each temporal lobe, often shrinks disproportionately; in frontotemporal degeneration the front of the brain thins first. A scan read as normal for age does not exclude early disease, and mild shrinkage does not confirm it. Context is everything.

Molecular imaging goes further. A PET scan tracks a radioactive tracer and can show reduced energy use in specific regions or, with amyloid or tau tracers, visualize the disease proteins themselves. These scans are generally reserved for uncertain cases or when treatment eligibility depends on the answer.

Cerebrospinal fluid analysis involves a lumbar puncture, a needle placed in the lower back to sample the fluid that bathes the brain and spinal cord. Amyloid and tau levels in that fluid can support or argue against Alzheimer’s disease, and the same sample screens for inflammation or infection. Mayo Clinic describes it as an option when the diagnosis is unclear or the person is young.

An EEG, which records the brain’s electrical activity, is added when seizures or a rapidly progressive condition are suspected. Genetic testing is uncommon and usually discussed with a counselor in the setting of strong early-onset family history.

What are some common memory disorders besides Alzheimer's disease?

Alzheimer’s disease is the most common cause of dementia; the World Health Organization estimates it accounts for roughly 60 to 70 percent of cases worldwide. It is still one entry on a longer list, and the others are what a neurologist is actively weighing during the exam. Dementia itself is an umbrella term for a decline in thinking severe enough to interfere with daily independence; it names the impact, not the cause.

Condition	Typical first change	Clues a neurologist looks for
Alzheimer’s disease	Trouble storing new memories	Gradual onset; cues do not help recall; word-finding difficulty; disorientation later
Vascular cognitive impairment	Slowed thinking, trouble planning	Stepwise decline; stroke history; strokes or white-matter changes on MRI
Lewy body dementia	Visual hallucinations, fluctuating alertness	Parkinsonian stiffness; acting out dreams during sleep; sensitivity to some antipsychotic medicines
Frontotemporal dementia	Personality or behavior change, or loss of language	Younger onset; memory relatively spared early; frontal or temporal shrinkage
Mild cognitive impairment	Measurable decline, independence intact	May stay stable, improve or progress; many possible causes
Normal pressure hydrocephalus	Walking difficulty	Gait change, urinary urgency, cognitive slowing; enlarged fluid spaces on imaging; potentially treatable

Mixed dementia, meaning Alzheimer’s changes alongside vascular damage, is common in older adults, which is one reason imaging findings and the clinical story are read together rather than separately. Rarer entries include alcohol-related brain damage, autoimmune encephalitis and prion disease, each with its own tempo and tests.

Names on this table are not a menu for self-diagnosis. They are what your neurologist is considering while watching you walk into the room and asking, oddly, about your dreams.

Mild cognitive impairment: the diagnosis that is not dementia

Somewhere between reassurance and a dementia diagnosis sits a term many families hear for the first time in a neurologist’s office: mild cognitive impairment, or MCI.

MCI means testing shows a measurable decline in one or more thinking skills, greater than expected for age and education, while the person still manages daily life independently. They may need more lists, more time and more double-checking, but the bills get paid and the stove gets turned off. That preserved independence is the dividing line from dementia.

What MCI does not mean is a verdict. Cleveland Clinic notes that roughly 10 to 15 percent of people with MCI progress to dementia each year, which also means most do not in any given year. Some remain stable for long stretches, and a proportion return to normal testing, particularly when a contributor such as depression, sleep apnea or a medication is addressed. Neurologists divide MCI into amnestic (memory-predominant) and non-amnestic types because the pattern hints at cause: amnestic MCI more often precedes Alzheimer’s disease, while non-amnestic patterns may lead elsewhere or nowhere.

Because MCI is a description rather than a single disease, the response is watchful and practical. Blood pressure, diabetes, cholesterol and smoking are managed vigorously, since what protects blood vessels tends to protect the brain. Hearing is checked and corrected. Physical activity, social engagement and sleep are treated as prescriptions rather than pleasantries. Repeat cognitive testing at intervals, often every 6 to 12 months according to Cleveland Clinic, answers the trajectory question.

MCI is also the stage at which some people become candidates to discuss newer Alzheimer’s-directed treatments, which require confirmation of amyloid in the brain. An MCI diagnosis may therefore prompt the biomarker testing described earlier rather than closing the evaluation.

What are the treatment options for memory loss in older age?

This question has two very different answers depending on what the evaluation found.

When a reversible contributor is identified, the treatment is the treatment of that condition: thyroid replacement, vitamin B12 repletion, a medication adjusted by the prescriber, a breathing device for sleep apnea, a hearing aid, psychotherapy or an antidepressant for depression, surgery for hydrocephalus. Improvement can be meaningful, though it is not guaranteed, and it can take weeks to months to judge.

When the diagnosis is Alzheimer’s disease or a related dementia, treatment aims to manage symptoms, slow decline where possible and support function. Three medication classes are in mainstream use, named here so readers recognize them, not as recommendations. Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) block the breakdown of acetylcholine, a messenger chemical depleted in Alzheimer’s disease; Mayo Clinic describes their effect as modest, temporary support of memory and attention. Memantine acts on a different messenger system, glutamate, and is generally considered in moderate to severe stages. Anti-amyloid monoclonal antibodies are infused treatments that bind and clear amyloid plaques; in early-stage disease they slowed decline by a limited but measurable amount in trials, require confirmed amyloid on PET or spinal fluid, involve regular MRI monitoring for a side effect called ARIA (brain swelling or small bleeds), and are not appropriate for everyone. Whether any of these fits a particular person is a decision for the prescribing neurologist, weighing heart rhythm, kidney function, genetics, other medications and the person’s own goals.

Non-drug treatment is not a consolation prize. Structured exercise, hearing correction, cardiovascular risk control, cognitive and social engagement, treatment of sleep disorders and management of depression have the best-supported record for maintaining function across the dementia spectrum. Caregiver education, home safety review and advance care planning are part of treatment too, and a good clinic treats them that way.

What the days and weeks after a memory evaluation usually look like

Most memory evaluations unfold over weeks rather than a single afternoon, and knowing the rhythm removes some of the dread.

In the first days after the initial visit, blood is drawn and an MRI or CT is scheduled. Results return in a staggered way; a reassuring scan report may arrive before the thyroid result, and a low B12 may be flagged before anyone has decided what it means. Resist reading each result in isolation. Putting them together is the neurologist’s job.

If neuropsychological testing is ordered, expect a separate appointment lasting several hours, sometimes split across two sessions, with a written report a few weeks later. Bring glasses and hearing aids, sleep beforehand and do not study; the point is an honest baseline.

A follow-up visit, typically a few weeks to a couple of months after the first, brings the pieces together. Three outcomes are common. A reversible cause is found and treated, with re-testing planned to confirm that thinking improves. The picture fits mild cognitive impairment, and a monitoring plan is set, commonly re-evaluation every 6 to 12 months as Cleveland Clinic describes. Or the findings support a specific dementia diagnosis, and the conversation shifts to treatment options, safety, driving, work, legal planning and support for the household.

Sometimes the honest answer is not yet certain. Early disease can be indistinguishable from stable MCI on a single assessment, and a neurologist who says so is being accurate, not evasive. The plan then is time and a repeat battery, occasionally supplemented by PET or spinal fluid testing if the answer would change management.

Through all of it, daily life continues. Nothing about the evaluation requires stopping work, giving up activities or altering medications on your own. Those decisions, if they come, are made together and with reasons.

What people often get wrong about memory loss and Alzheimer's testing

Memory loss attracts confident misinformation, and correcting a few pieces of it changes how people approach the evaluation.

Memory loss is just part of getting old. Slowed recall is; dementia is not. The WHO estimates more than 55 million people live with dementia worldwide, a large number that is still a minority of older adults. Treating progressive decline as inevitable delays the search for causes that can be fixed.

There is no point getting tested because nothing can be done. Even setting aside Alzheimer’s-directed medicines, an evaluation can uncover thyroid disease, B12 deficiency, depression, sleep apnea, medication effects or hydrocephalus, each treated differently and none improved by being ignored. A diagnosis also lets a family plan while the person can still voice their own wishes.

A normal score on the memory test means everything is fine. Screens miss early change in highly educated people and flag healthy people with less schooling or a poor night’s sleep. They are a triage step.

An MRI will show whether it is Alzheimer’s. Structural scans rule things out and reveal patterns; on their own they do not diagnose Alzheimer’s disease. Molecular imaging and spinal fluid come closer, and even those are interpreted alongside the clinical story.

A supplement or brain-training app will fix it. No supplement has convincing evidence of preventing or treating dementia, and NIH advises caution about products marketed for memory. Exercise and hearing correction have far better evidence than anything sold in a bottle.

If a parent had it, I will get it. Most Alzheimer’s disease is not directly inherited. Family history raises risk modestly; strongly inherited early-onset forms are rare.

Sudden confusion is just dementia getting worse. Sudden change is delirium until proven otherwise, and delirium is an emergency.

Questions to ask your care team

A memory evaluation goes better when the family arrives with questions, partly because the person being evaluated may not remember to ask them. Write these down and bring a pen.

• What are the possible explanations for what we have described, and which concern you most?
• Which of those causes could be treatable, and which tests will look for them?
• Is this mild cognitive impairment, dementia or too early to say, and what would change your mind?
• How should I interpret the cognitive screen score given my education and background?
• Do you recommend neuropsychological testing, imaging or spinal fluid analysis, and how would each change the plan?
• Are any of my current medications, including over-the-counter ones, likely to be affecting my thinking?
• If a treatment is being considered, what does the evidence show it does and does not do, what monitoring is involved, and what are the alternatives?
• Is it safe for me to keep driving, working or managing my finances for now, and how will we revisit that?
• When should we come back, what should we track in the meantime, and what would prompt an earlier visit?
• What support, from caregiver education to legal and advance-care planning, should we start on now?

Two more habits pay off. Ask for copies of test results and the visit summary, so a future clinician can compare rather than start over. And ask who to call between appointments when something changes; a clinic’s nurse line often resolves a worry faster than waiting for the next visit.

One caution about the medication question: the answer may be that a drug is contributing, but the change should be made by the prescriber, who knows why it was started and what replacing it involves. Stopping something abruptly at home can create a new problem while trying to solve the old one.

When to call your doctor

Most memory concerns can wait for a scheduled appointment. Some cannot, and the distinction comes down to speed and company: how fast did it change, and what arrived with it?

Call emergency services immediately for sudden confusion, trouble speaking or understanding, facial drooping, weakness or numbness on one side, sudden severe headache, or loss of consciousness. These can signal stroke or bleeding, where minutes matter. The same urgency applies to confusion after a head injury or fall, even a minor one in an older adult, and to a first-ever seizure.

Contact your doctor the same day for confusion or disorientation that has developed over hours or days, especially with fever, a suspected infection, a new medication, dehydration or recent surgery; this pattern suggests delirium, which is medical, treatable and time-sensitive. New hallucinations, sudden agitation or drowsiness, a rapid change in walking with new incontinence, or unexplained decline over a few weeks also warrant prompt contact.

Book a routine appointment for memory or thinking changes that have persisted for months, are noticed by others, are affecting bills, medications, cooking or driving, or arrive with low mood, sleep changes or withdrawal from usual activities. Mention it even if you suspect stress; the clinician needs to hear it to weigh it.

If someone with a diagnosis is living alone and there is a safety concern, such as a stove left on, wandering or a medication mix-up, raise it with the care team without waiting for the next visit.

Every threshold above is a reason to make contact, not a diagnosis. What happens next, whether tests, referral, treatment, or reassurance and a follow-up date, is the treating team’s decision, made with you and the people who know you best.

Frequently asked questions

What will a neurologist do for memory loss?

A neurologist takes a detailed history from you and someone who knows you, performs a neurological examination with particular attention to walking, administers a brief cognitive screen, reviews every medication, and orders blood tests and brain imaging to rule out treatable causes. Depending on findings, they may add neuropsychological testing, PET imaging or spinal fluid analysis, then discuss whether the picture fits mild cognitive impairment, a specific dementia, or a reversible condition.

What is the best doctor to see for memory loss?

Start with your primary care clinician, who can screen, order initial blood work and refer onward. A neurologist is the specialist for distinguishing between brain diseases and interpreting imaging; a geriatrician suits people with several coexisting conditions; a neuropsychologist provides detailed cognitive testing. Many memory clinics combine these roles, so asking your primary care doctor about a memory clinic referral is often the most efficient path.

What is the neurologist memory test like?

It is a short, structured screen of several thinking skills, often the MoCA or MMSE, taking a handful of minutes. Tasks include recalling a word list, drawing a clock, naming animals, repeating sentences and stating the date. The score is a signal rather than a diagnosis and is interpreted against your education and background. If concerns remain, longer neuropsychological testing over several hours provides a more detailed profile.

What are some common memory disorders other than Alzheimer's disease?

Vascular cognitive impairment from strokes or small-vessel disease, Lewy body dementia with hallucinations and parkinsonian features, frontotemporal dementia affecting behavior or language, and mixed dementia are the main degenerative alternatives. Mild cognitive impairment describes measurable decline with independence preserved. Potentially reversible mimics include normal pressure hydrocephalus, depression, thyroid disease, vitamin B12 deficiency, sleep apnea, medication effects and delirium.

What are the reversible causes of memory loss a neurologist checks?

The usual list includes delirium from infection or dehydration, depression, sedating or anticholinergic medications, underactive thyroid, vitamin B12 deficiency, abnormal sodium or calcium, kidney or liver dysfunction, obstructive sleep apnea, heavy alcohol use, uncorrected hearing loss, normal pressure hydrocephalus and chronic subdural hematoma. Blood tests, a medication review and brain imaging cover most of these, which is why they are ordered before any Alzheimer’s-specific testing.

Can a neurologist diagnose Alzheimer's in one visit?

Rarely. NIH’s National Institute on Aging notes that no single test confirms Alzheimer’s disease; the diagnosis is built from history, examination, cognitive testing, blood work and imaging assembled over weeks. A first visit usually ends with a plan for tests and a follow-up appointment. Some people leave that second visit with a clear answer; others are asked to repeat testing after several months because early disease and stable mild cognitive impairment can look alike.

Does mild cognitive impairment always turn into dementia?

No. Cleveland Clinic reports that roughly 10 to 15 percent of people with mild cognitive impairment progress to dementia each year, so in any given year most do not. Some remain stable for years and some return to normal testing, especially when a contributor such as depression, sleep apnea or a medication is addressed. Regular re-evaluation, often every 6 to 12 months, is how the trajectory becomes clear.

Can stress, anxiety or depression cause memory loss?

Yes. Depression and anxiety impair attention and retrieval, which shows up as forgetfulness, poor concentration and word-finding trouble. This pattern often improves when hints are offered and when the mood disorder is treated. Mayo Clinic also notes that depression and Alzheimer’s disease can coexist, so a clinician will screen for mood at the same time as ordering other tests rather than assuming one explanation excludes the other.

Is there a blood test for Alzheimer's disease?

Blood tests measuring amyloid and tau proteins are entering specialist practice, but NIH’s National Institute on Aging describes them as still being validated for routine clinical use, and they are interpreted alongside the clinical picture rather than alone. Routine blood work in a memory evaluation looks for treatable contributors such as thyroid disease and vitamin B12 deficiency. Ask your neurologist whether a biomarker test would change decisions in your situation.

What are the treatment options for memory loss in older age?

It depends on the cause. Reversible contributors are treated directly, from thyroid replacement to sleep apnea therapy or a prescriber-led medication change. For Alzheimer’s disease, options include cholinesterase inhibitors, memantine and, in early confirmed disease, anti-amyloid antibody infusions with MRI monitoring, all decided by the prescribing neurologist. Exercise, hearing correction, cardiovascular risk control, social engagement, sleep treatment and caregiver support are part of treatment for every diagnosis.
